First off it is not going to start if you reverse the cables. If you do reverse them you can do no damage at all or you can actually blow the battery up causing injury to anyone near it. The battery cables can heat up so quickly that they melt in your hand especially if they are small cables. You may also blow the main fuse in the car or you can do serious damage to the electronics in the car. Any number of bad things can happen it just depends on the vehicle.

Connect to two wires you have to the the spade connectors and forget the ground connector. The spade connector wires should be black and white. Black to gold and white to silver. If the wires coming from the heater happen to be red and white, then red goes to black. You could buy a simple lamp cord which has only tow wires.

In electrical circuits, white wires are typically used as neutral wires, green wires are used as ground wires, and black wires are commonly used as hot wires.
You would have to provide more info to be certain what your problem is. Typically a black and white wire would connect to the two wires on the light fixture. The fixture should also be controlled by a switch that "breaks" the black (Hot Wire) to turn off the fixture. If you have a volt meter you can see if there is 120Volts between the black and white wires with switch on. If there is a single white wire going to fixture (Neutral), where is the "black wires tied" to. Maybe one of the black wires has broken off the fixture.
